What do the political parties know about me?

At some point for some reason I signed up for newsletters from the Open Rights Group. After the general election they requested people write into the various political parties and request copies of the personal data that was held on them. This sounded interesting so I did it. So far:

• Change UK know nothing! - arguably the story of the party.
  
• UKIP doesn't think it knows anything but thinks it might have sent me a leaflet in which case it was just sending a leaflet to all addresses in the area not to me personally. This was a long response which sounded vaguely panicked, which was amusing if nothing else.
  
• The Lib Dems noted they were getting a lot of requests via Open Rights group and wanted to know if I was really asking (I can't recall if I responded to this or not). I probably didn't since I haven't heard anything further and, anyway, their data is likely to include something along the lines of "you are a member so *duh*!
  
• The conservatives have data from the electoral role, the marked register from the polling station for 2014, my data of birth which, rather implausibly, they claim to have obtained when canvassing (also nationality and gender which is more plausible). Then they have a shed ton of inferences made from this data using models (and, we think, probably access to land registry). This is fascinating. They have percentages for how likely I am to read various newspapers (most likely The Guardian, least likely The Mirror). They obviously have several different models since they think I both do and don't have children. They are more or less correct about my income but incorrect about the value of the outstanding mortgage on the house. They think I am a housewife or work part time. I've scored 0 on a scale of 1-7 for how likely I am to vote (?) - even more excitingly I've scored 14 on a scale of A-G for how likely I am to be a Conservative. They think they shouldn't try to have a conversation with me on the doorstep.
  

I've not heard from any of the other parties and, at this point, I've forgotten which I requested data from, though I would have expected Labour, Green and Brexit to have been on the list and their responses are conspicuous by their absence.
